Suspension.
In fact, it was a mixture of fine particles of medicine that did not melt in water but was completely mixed with water.
After the realgar powder was taken out of the wall-breaking machine, Fang Qiu continued to add a lot of water to the container and began to stir. Then he took out the upper half of the suspension and poured it into the first container.
Then, he continued to add water and stirred to take out the liquid.
Then he stirred again and took out the liquid.
And so on.
Although it seemed a little inexplicable, Fang Qiu did it very carefully and did not dare to be careless at all.
Over there.
Seeing Fang Qiu's processing technique, Doctor Niu, who had already cleaned the tea set and was ready to start making tea, couldn't help but smile and nod gently.
Others couldn't understand it, but he could see it very clearly.
Many Chinese Medicine doctors with poor foundation would almost slack off in this step when processing realgar.
This seemingly boring step was actually to remove the impurities in the realgar. Although the impurities had already been removed before processing, at that time, only the impurities on the outside of the realgar were removed. There were still some impurities inside the realgar.
These impurities also had to be removed.
After the realgar was ground into powder, its weight in the water was not as heavy as the weight of the impurities contained in the realgar. Therefore, it could only be repeated until all the impurities sank to the bottom of the water and all the realgar suspension fused with the water was extracted.
It seemed very simple, but it was very boring to repeat it again and again.
In this kind of repetition.
Fang Qiu was not impatient at all. Instead, he did it very carefully.
It was this that made Doctor Niu feel particularly satisfied.
After about half an hour.
Fang Qiu completely removed the impurities.
Finally, Fang Qiu combined all the suspended liquid and put it in a transparent container. He put it aside and did not touch it.
He only needed to wait for the water to completely precipitate, completely separate the water from realgar, dry it, and then grind it by hand.
However.
It would take a long time for the realgar suspension to precipitate.
It was precisely because of this that Fang Qiu chose the processing method of realgar first.
In fact.
When he saw the ten medicines given by Doctor Niu, the processing method of each medicine had already appeared in Fang Qiu's mind. If it was just a test of memory of the processing method, Fang Qiu could easily say all the processing methods of the ten medicinal materials without missing a word.
However, what Holy Doctor Niu wanted to test was the operation.
Therefore, Fang Qiu could only do it by himself. He fully displayed the processing method that he thought was appropriate in front of Doctor Niu.
For the first medicine, realgar, Fang Qiu directly used the Water Flying Method, the nemesis of all kinds of medicinal materials.
Whether it was ancient times or modern times.
Cinnabar, realgar, and other medicinal herbs were all processed using this method.
The Water Fly Method made use of the insoluble nature of the metal and stone herbs. It ground the herbs repeatedly and made use of the different suspensibility of the fine and coarse powders in the water to separate the extremely fine powder. At the same time, the toxicity and impurities in the herbs were removed.
On this side.
When the suspension began to settle down, the temperature dropped.
Fang Qiu did not want to waste a minute, so he directly began to process the second medicinal material.
The second taste.
Fang Qiu chose Bambi.
Spotted beetle is the dried whole body of the southern large spotted beetle or the small yellowish-black spotted beetle. In summer and autumn, it is caught before the morning dew is dry, placed in a container to suffocate or scald to death, and then dried in the sun.
In ancient times.
There are also many ways to prepare Bambi.
In the Jin Dynasty, there were methods of moxibustion, stir-frying, burning, and so on.
In the Liu Song Dynasty, there were methods of stir-frying glutinous rice and small pockmarks together.
In the Song Dynasty, there were methods of brewing wine, stir-frying bran, stir-frying bean flour, boiling in vinegar, moxibustion in vinegar, and stir-frying croton and rice together.
In the Ming Dynasty, there were records of stir-frying with oysters, stir-frying with wheat flour, and stir-frying with bran.
In the Qing Dynasty, there were also methods of steaming, swill with rice, stir-frying with clay, and so on.
And in modern times.
Most of them only used one method of processing.
What Fang Qiu was going to use was naturally the modern method.
He picked up Bambi and had a look.
Fang Qiu immediately walked into the material room and began to look for materials inside.
After a long time.
He walked out of the material room and grabbed a stove, a pot, a sieve, and a bag of glutinous rice.
On this side.
Holy Doctor Niu had already poured tea.
After a careful look and seeing the materials and tools that Fang Qiu took out, he nodded with a smile again.
It seemed that the method that Fang Qiu used to prepare Bambi should be the same as he imagined.
Fang Qiu, who was preparing, did not observe Holy Doctor Niu's expression at all. Instead, he focused all his energy on the processing of the medicinal materials.
This time, after taking out all the tools and materials needed, Fang Qiu did not immediately start to work. Instead, he returned to the material room again and took out some Bambi according to the proportion.
When he entered the material room for the first time, Fang Qiu found that there were a lot of medicinal materials in the material room, at least 20 or 30 kinds, and the quantity of each kind was not small.
And there was only one of the ten medicinal materials selected by Holy Doctor Niu. Bambi was different from realgar. It was impossible to process only one, so he could only take more to process together.
After taking out Bambi.
Fang Qiu began to carefully take out the head, feet, and wings of each Bambi, as well as the magazines on its body.
After all of them were removed.
Fang Qiu began to light the fire and the stove.
He controlled the fire in the stove to the level of a gentle fire, and then heated the pot first.
While heating the pot, Fang Qiu mixed the picked Bambi with the glutinous rice in a certain proportion. When the pot was hot, he put Bambi and the glutinous rice into the pot and began to stir-fry.
It was different from the previous water flying method.
This time, the reason why he chose to heat the Bambi was that heat could reduce the toxicity of the medicinal materials and enhance its curative effect.
However, this method of stir-frying was difficult to control the degree of heat. Many people thought that the heat needed experience to control, but it was not the case.
When stir-frying Bambi, as long as the white glutinous rice was added and heated together, when the glutinous rice turned brown, it meant that the medicinal materials had been heated to the critical point, which meant that the purpose of processing had been achieved and the heating could be stopped.
Simply put.
The addition of white glutinous rice would not affect the medicinal properties of the medicinal materials, but it could also act as a "thermometer".
Originally, with Fang Qiu's strength, it was very easy to control the heat to make a medicine. But now he was undergoing an assessment, so he could not use other abilities. Once he fully showed his ability, he was afraid that it would scare Holy Doctor Niu.
After all, what Holy Doctor Niu wanted to see was that he could do it step by step.
Fang Qiu stir-fried in time.
He didn't know how long it had been.
When the glutinous rice in the pot showed yellow-brown, Fang Qiu stopped stir-frying.
Then, he lifted the pot and poured the rice and Bambi into the prepared sieve. He used the sieve to sift out the rice, leaving only Bambi.
Then he spread out Bambi in the sieve and let it cool.
Put Bambi.
Fang Qiu turned his head to look at the suspended realgar and found that the suspended realgar was still turbid. He immediately turned his head to look at the third medicinal material.
The third one.
Leech!
Leech, commonly known as leech, was recorded in Shennong's Classic of Materia Medica. It had high medicinal value. It grew and multiplied in inland freshwater areas. It was a traditional special medicinal aquatic animal in Huaxia. Its dried products were used as medicine in traditional Chinese medicine. It had the effect of treating stroke, high blood pressure, removing blood stasis, amenorrhea, and injuries from falls.
In ancient times, there were many ways of processing leeches.
In the Han Dynasty, there were methods of boiling and washing with warm water to remove the fishy smell.
In the Song Dynasty, there were methods of slightly stir-frying to make it slightly yellow, slightly simmering to make it yellow, stir-frying to scorch, soaking in water to remove the blood, stir-frying with lime and then boiling, soaking the rice overnight and then drying, frying with winter lard to make it brown, baking, and making it musk.
In the Yuan Dynasty, salt stir-frying was added.
In the Ming Dynasty, moxibustion appeared, and in the Qing Dynasty, the method of stir-frying with sesame oil was added.
However.
Compared with these ancient processing methods, the modern processing methods were obviously easier.
This time.
Fang Qiu didn't observe the leeches first. After thinking for a while, he immediately walked into the material room and took out a cutting board, a kitchen knife, and a bag of talcum powder.
After all the materials and tools were ready.
Fang Qiu took enough leeches from the material room.
Originally, the first step was to wash the live leeches, cut them off, and dry them.
However.
The leeches prepared by Doctor Niu were dried leeches, which saved Fang Qiu a lot of trouble.
After all the materials were ready, Fang Qiu first cleaned the pot that had just been used to process Bambi. Then he put it on the stove and let the temperature of the stove burn the pot dry. Then he put the talcum powder into the pot and began to stir-fry.
He kept heating and stir-frying until the talcum powder was flexible. Then he put all the leeches into the pot and began to stir-fry faster.
Fang Qiu didn't stop until the leeches were slightly bulging and showed a yellow-brown color. He put the pot down.
He put away the cooled Banshee in the sieve next to him, then poured the talcum powder and leeches into the sieve. He poured the talcum powder into the sieve, leaving only the leeches, and put them in the sieve to cool.
After doing all this.
Fang Qiu was a little relieved.
However, when he looked at the next medicine, he couldn't help but smile bitterly.
Human White!
Human White was a solid substance that naturally took advantage of human urine.
In ancient times, there were only a few processing methods.
In the Song Dynasty, there was the charcoal processing method. In the Ming Dynasty, forging and stir-frying were added. In the Qing Dynasty, there was the wine jujube treatment method and the fire and vinegar quenching method.
However.
The modern processing methods were not as simple as those before.
The most critical problem was time!
Because the processing of Human White needed to remove impurities. It needed to be soaked in clean water and rinsed for 10-15 days. The water needed to be changed twice a day and it had to be exposed to the sun and dew at night.
However, if it really took ten days, Fang Qiu couldn't wait.
"Is it Human White and Human Yellow?"
Over there.
Seeing that Fang Qiu suddenly stopped, Doctor Niu immediately glanced at the two medicinal materials in front of Fang Qiu. Then he said with a smile, "These two medicinal materials, you can go through the process. It doesn't have to take so long."
"Okay."
Hearing that, Fang Qiu was a little relieved.
Then he immediately started to go through the process. That was, according to the modern processing method, he could shorten the time and go through the process once.
